We assume that the curvature of the trabeculae indicates the cranial direction; no exceptions to this have been reported for pterosaurian head crests.
The widths of individual trabeculae are variable, but none is greater than 1.0 mm.
The maximum preserved height of the exposed trabeculae is 15 mm, and there are between 12 and 14 trabeculae per 10 mm.
During development, their anterior ends fuse and form the "trabecula communis".
In the 19th century, the neologism "trabeculum" (with an assumed plural of "trabecula") became popular, but is less etymologically correct.
The striae most likely consist of linear trabeculae that support the crest internally.
Loading plays an important role in the maintenance of cancellous connectivity (through the remodelling process), and in the orientation of the trabeculae and the periosteal apposition (through the modelling process).
They can be composed of other materials; in the heart, for example, muscles such as trabeculae carneae and septomarginal trabecula form similar structures.
